m2eclipse error

Question

I am developing a web application with Eclipse and I generate the project with a maven archetype.

When I enable maven dependency management, Eclipse mark some errors

Answer 1

I had the same problem but with an other cause. The solution was to deactivate Avira Browser Protection (in german Browser-Schutz). I took the solusion from m2e cannot transfer metadata from nexus, but maven command line can. It can be activated again ones maven has the needed plugin.
